Handing me over to Saya Recoveries after 10months

I upgraded my red tag to a black tag, then my children's 2 tags were cancelled. The gym apologised and said they will fix it. The end of that month a double debit order went off, since the gym did not notify me, I reversed one amount as I did not know if I was paying for 2 memberships after the upgrade now JUNE 2015. Due to the reversal my tag was disabled, so I could not enter the gym, Saya recoveries contacted me and said I should pay R650 and my tag was not disabled as it was a double payment as per my contract and I rep**** that I paid double December 2014, their reply was that they can either double deduct Dec/June, but I received NO notification. When I went to the gym, they said I should NOT pay Saya, but the gym directly an amount of R800 and that my tag was no longer active, oh and I should fill in a new debit order form, mine was lost. I explained to the gym that I received No notifications from them, they did not suffer any losses as my tag was disabled and why should I pay for their mistake. That was August 2015, no communication after that. Saya Recoveries today threatens to take me to court and itc.,but my contract expired March 2016, say I must pay cancelation fees??
